[Fedora-legal-list] How to write License field for packages bundling mutliple others

[Igor Gnatenko]

In Rust world we package all crates as source code in -devel packages.
Then we use them to build the real applications.

Some time ago, someone noticed that we don't put licenses of those
-devel packages into a resulting RPM with app which is fair.

However, I'm not entirely sure how to properly write the License tag.
What should be there if -devel packages have:

* ASL 2.0
* ASL 2.0 or Boost
* ASL 2.0 or MIT
* ISC
* MIT
* (MIT or ASL 2.0) and BSD
* Unlicense or MIT

Is it correct to put License: ISC and MIT and ASL 2.0 and BSD?
